La connaissance scientifique possède en quelque sorte des propriétés fractales : nous aurons beau accroître notre savoir, le reste -- si infime soit-il -- sera toujours aussi infiniment complexe que l'ensemble de départ.
En anglais : "I believe that scientific knowledge has fractal properties; that no matter how much we learn; whatever is left, however small it may seem, is just as infinitely complex as the whole was to start with. That, I think, is the secret of the Universe." (in 'I, Asimov: A Memoir' )
